SSL4120  
Resonant power supply controller IC with PFC for LED  
lighting  
Rev. 2 — 1 November 2012  
Product data sheet  
1. General description  
The SSL4120 integrates a Power Factor Corrector (PFC) controller and a controller for a  
Half-Bridge resonant Converter (HBC) in a multi-chip IC. It provides the drive function for  
the discrete MOSFET in an up-converter and for the two discrete power MOSFETs in a  
resonant half-bridge configuration.  
Efficient PFC operation is achieved by implementing functions for Quasi-Resonant (QR)  
operation at high-power levels and QR with valley skipping at lower power levels.  
OverCurrent Protection (OCP), OverVoltage Protection (OVP) and demagnetization  
sensing ensure safe operation under all conditions  
The HBC module is a high-voltage controller for a zero-voltage switching LLC resonant  
converter. It contains a high-voltage level shift circuit and several protection circuits  
including OCP, open-loop protection, capacitive mode protection and a general purpose  
latched protection input.  
The high-voltage chip is fabricated using a proprietary high-voltage Bipolar-CMOS-DMOS  
power logic process enabling efficient direct start-up from the rectified universal mains  
voltage. The low-voltage Silicon-On-Insulator (SOI) chip is used for accurate, high-speed  
protection functions and control.  
The SSL4120 controlled PFC circuit and resonant converter topology is very flexible. It  
can be used for a broad range of applications over a wide mains voltage range.  
Combining PFC and HBC controllers in a single IC makes the SSL4120 ideal for  
controlling compact power supplies in lighting applications, such as LED drivers.  
Using the SSL4120, highly efficient and reliable power supplies providing over 100 W can  
be designed easily which use the minimum of external components.  
Remark: Unless otherwise stated, all values are typical.
